I have the PA1x Pro, which is, of course, the big brother to the PA800.
What I have done is I find a style, tempo, STS etc. that goes with the song I'm working on (in my case, a praise and worship song), then write it into the songbook as a song. I have several songs with the same styles, but with different tempos and by using different variations, I can make a pretty wide variety in the bands. Tempo can sound like a copmpletely different style. I then have all of our songs for our ministry in one list under the ministry name for rehearsal purposes then have another list called "Setlist" where I place songs for each service so thati live I can go between songs for that service quickly.
Hope this helps.
"Sing"cerely,
Jeff
